Abstract
Acetic acid bacteria (AAB) are obligately aerobic Gram-negative bacteria. Known for their ability to oxidize ethanol to acetic acid and robust tolerance to acetic acid, AAB have been widely used in industrial vinegar fermentation. Besides the incomplete oxidative ability, investigation of their resistance mechanisms to acetic acid is intriguing and crucial for high titer vinegar production. In this review, we evaluated a variety of resistant pathways involved in carbohydrate metabolism, protein metabolism, lipid metabolism, and stress response based on genomics and proteomics investigations in AAB. Specifically, the discovery in modules related to quorum sensing (QS) system in Komagataeibacter species and the emerging genome data of AAB opens a new window to screen acid resistance regulatory networks, which may promote industrial strain breeding and fermentation optimizing. We reviewed the latest research progress of quorum sensing in acetic acid bacteria based on the brief introduction of genomic and proteomic studies.
